Jose Mendez, a citizen of El Salvador, petitions for review Of an order of the Board of Immigration Appeals, which affirmed an immigration judge’s decision and denied him asylum, withholding of removal, and relief under the Convention Against Torture (CAT). 1 After careful review, we find no basis for reversal, as the denials of relief were all supported by substantial evidence on the administrative record as a whole. See Khrystotodorov v. Mukasey, 551 F.3d 775, 781-84 (8th Cir. 2008) (substantial-evidence standard for asylum claim; denial of asylum dictates same outcome on withholding-of-removal claim and CAT claim based on same underlying factual allegations). Accordingly, we deny the petition for review. See 8th Cir. R. 47B.
